With a growing need and awareness of energy efficiency, many household fixtures have been redesigned to fit a green model. One of the first steps toward energy efficient homes was the halogen light bulb, which offered the same amount of light as the traditional incandescent bulb, but for a fraction of the energy. Recent developments in lighting technology have led to the use of LED's (light emitting diodes) in household bulbs, which are able to consume a fraction of the already efficient halogen bulb. Making the switch to LED bulbs is a very straightforward task, and can be completed by anyone.
Turn off light (if not already off) and allow time to cool to room temperature.
Carefully grip the halogen bulb and gently twist it counter-clockwise until it can be pulled from the light socket. These bulbs can be stored for later use or discarded.
Insert the new LED bulb into the socket and gently turn it clockwise until tight. Turn the light on to make sure the new bulb is working properly and is the proper strength, replace as necessary.
Repeat steps 1 through 3 on remaining light sources.
